Lighting Assessment
Turn your building’s light into a case your board can defend.
Independent experts measure the light your occupants actually live under, then translate it into the financial language that survives value engineering. We don’t sell fixtures — we quantify what your light is costing you, and what better light is worth.
Why Earthlight
Independent lighting experts, translating research into financial intelligence
Experienced
Over a decade translating circadian lighting science into the financial language that owners, operators, and boards actually use to decide.
Research-backed
Our models are built on the most credible peer-reviewed lighting science and the recognized measurement standards the field has converged on.
Product-neutral
We're paid for the analysis, not the fixtures. The assessment is finished before any vendor is in the room, and when we help you source against it, a proposal clears on the performance it delivers — whoever it comes from.
The engagement
Two phases, from measurement to defensible case
The app models the Human ROI of your lighting from what you tell it. The assessment is the evidence-grade version: experts on site, measuring your actual light, building a case that holds up in procurement.
Phase 1
Light Environment Assessment
An on-site visit. We document your building's actual light: lux levels, color temperature, spectra, the timing of light exposure across the occupied day, and the quality of darkness at night. We map circadian-disruption risk area by area, population by population.
You receive a written summary of where the building stands — in language your architect, clinical lead, and facilities team can all read.
Phase 2
Earthlight Facility Report
The assessment data expressed as economic cost and opportunity. What is the current light environment costing you — in outcomes, staff performance, and institutional risk? And what would circadian-optimized lighting change, in measurable, defensible terms?
A report built to inform your board and defend the lighting specification from value-engineering cuts.
Phase 1 — Assessment
- Current lux levels and spectral readings
- Timing of light exposure across the occupied day
- Darkness quality at night
- Circadian-disruption risk mapped by area and population
- Written summary for architect, clinical, and facilities teams
Phase 2 — Facility Report
- Economic cost of the current light environment
- Impact on human outcomes and performance
- Staff performance and institutional-risk analysis
- A measurable, defensible case for circadian-optimized lighting
- Formatted for board and procurement review
Why timing matters
The economic case has to exist before the specification is written — not after it has already been challenged. Engage while the design is still open, and good lighting enters the budget conversation with numbers behind it.
Put the evidence on the table.
An independent assessment and a Facility Report your board can act on — before the specification is written.
